Lower Limits:NOT DEFINED
Upper Limits:NOT DEFINED
Extinguishing Media:NOT APPLICABLE.
Fire Fighting Procedures:STANDARD PERSONAL PROTECTIVE EQUIPMENT FOR
STRUCTURAL FIREFIGHTING.
Unusual Fire/Explosion Hazard:TREATED FUMED SILICA CAN BUILD STATIC
ELECTRICAL CHARGES WHEN SUBJECT TO FRICTION. CAB-O-SIL TS-720
TREATED FUMED SILICA IS AN INORGANIC DUST & WILL NOT CREATE NOR
SUPPORT CONDITIONS THAT WOULD RESULT IN A DUST EXPLOSION OR FIRE.

Spill Release Procedures:SPILLS MAY BE COLLECTED, PREFERABLY BY VACUUM,
AND PLACED IN SUITABLE CONTAINER FOR DISPOSAL.

Handling and Storage Precautions:HANDLING: VENTILATE WORK AREA IF
NECESSARY ESPECIALLY DURING REMOVAL OF PACKAGING. TAKE
PRECAUTIONARY MEASURES AGAINST POSSIBLE BUILDUP OF ELECTROSTATIC
CHARGE. ASSESS MANUAL HANDLING OF BAGGED PRODUC T; TAKE SUITABLE
PRECAUTIONS.
Other Precautions:STORAGE: PRODUCT SHOULD BE STORED IN A COOL, DRY
LOCATION & AWAY FROM VIOLATILE CHEMICALS. AVOID STORAGE IN HIGH
TEMPERATURES. *SPECIAL PRECAUTIONS: AVOID HIGH TEMPERATURES. AVOID
CREATING DUST. CLEA N UP SPILLS PROMPTLY. IF ODOR DETECTED
VENTILATE AREA.

Respiratory Protection:APPROVED DUST/MIST RESPIRATOR RECOMMENDED FOR
CONCENTRATIONS ABOVE APPLICABLE EXPOSURE LIMIT.
Ventilation:USE GENERAL OR LOCAL EXHAUST VENTILATION TO MEET EXPOSURE
LIMIT REQUIREMENTS.
Protective Gloves:BARRIER CREAM APPLICATION PRIOR TO SKIN EXPOSURE MAY
ASSIST.
Eye Protection:SAFETY GLASSES WITH SIDE SHIELDS OR GOGGLES RECOMMENDED
TO PREVENT EYE CONTACT.
Other Protective Equipment:PROTECTIVE CLOTHING: NONE REQUIRED. FOUNTAIN
Work Hygienic Practices:WASH EXPOSED SKIN FREQUENTLY. GOOD PRACTICES
SHOULD BE FOLLOWED IN REGARD TO WORK CLOTHING.
Supplemental Safety and Health
PERSONAL PRECAUTIONS: WEAR GOGGLES IF RELEASE CREATES CONDITIONS WHERE
EYE CONTACT IS PROBABLE. IF AIRBORNE DUST CONCENTRATIONS EXCEED THE
APPLICABLE EXPOSURE LIMIT, THEN AN APPROVED RESPIRATOR FOR DU
ST.MIST IS RECOMMENDED.

Waste Disposal Methods:TREATED FUMED SILICA IS NOT A HAZARDOUS WASTE.
DISPOSE OF IN LANDFILL OR BY INCINERATION IN ACCORDANCE WITH
INTERNATIONAL, NATIONAL, U.S., FEDERAL AND LOCAL LAWS AND
REGULATIONS.

Toxicological Information:CHRONIC INHALATION EFFECTS: LONG-TERM
INHALATION ANIMAL STUDIES INVOLVING A VARIETY OF INSOLUBLE
PARTICLES HAVE RESULTED IN CHRONIC INFLAMMATION, LUNG FIBROSIS &
LUNG TUMORS IN RATS. TUMORS WERE NOT O BSERVED IN SIMILAR STUDIES
USING OTHERANIMAL SPECIES (I.E., MOUSE & HAMSTER). MOST INHALATION
TOXICOLOGISTS FEEL THE TUMOR RESPONSE IS UNIQUE TO RATS & NOT
RELEVANT TO HUMAN EXPOSURE. TREATED SYNTHETI C FUMED SILICA WAS NOT
USED IN THESE STUDIES. THE RESEARCHERS WHO CONDUCTED THE ABOVE
STUDIES FELT THE ADVERSE REACTIONS IN THE RAT WERE DUE TO HIGH
EXPOSURE LEVELS OF INSOLUBLE DUSTS OVERWHELMING THE LUNG CLEARANCE
MECHANISMS.
